 DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION
The battery compartment door 10 shown in FIG. 1 is used to locate a battery 12 inside a hearing aid device 16 for electrical connection to an electric circuit 14, as shown in FIGS. 2 and 3. Preferred embodiments of the battery compartment door 10 are hereafter described with reference to the hearing aid device 16. However, the battery compartment door 10 can be used to locate the battery 12 inside any other suitable electronic device.
The battery compartment door 10 includes a tubular cradle 18 that is open at both ends 22. The cradle 18 is shaped to receive a positive terminal end 20 of the battery 12 through either open end 22. The tubular sidewall of the battery 12 corresponds to the shape of the inner tubular surface 24 of the cradle 18 and the battery 12 is secured in the cradle 18 by frictional engagement.
The battery 12 is a standard button watch battery that is generally cylindrical in shape. The positive terminal of the battery 12 includes an end 20 of the battery 12 and a cylindrical sidewall. The negative terminal of the battery is located on the other end 26 of the battery 12.
A section of the cradle 18, including the inner tubular surface 24 and the upper section 30, is preferably wholly or partly made of an electrically conductive polymer. The electrically conductive polymer is preferably a mixture of polymer (PC/PA/PBT/PMMA or PE) and reinforced by metal powder, carbon. Alternatively, said section of the cradle 18 is wholly or partly made any suitable electrically conductive material. When a battery 12 is inserted into the cradle 18 in the above-described manner, the positive terminal 20 of the battery 12 is in electrical communication with the electrically conductive inner tubular surface 24 of the cradle 18. The cradle 18 is thereby electrically coupled to the positive terminal 20 of the battery 12. The negative terminal 26 of the battery 12 is electrically connected to existing metal contact 34 that extends from the electric circuit 14 towards the battery compartment door 10 when the door 10 is closed. Preferably, the cradle 18 is electrically isolated from the negative terminal end 26 of the battery 12. The other parts of the battery compartment door 10 are made of a non-conductive material such as ABS or PP.
The battery compartment door 10 is hingedly connected to a bottom section 27 of the device 16 by an axle 28 that extends through an aperture 29 in the door 10. The door 10 can rotate about the axle 28 so as to move towards and away from a main body of the device 16. The battery 12 can be loaded into the cradle 18 of the door 10 by rotating the door 10 away from the body of the device 10 to an open position, as shown in FIG. 4. In doing so the cradle 18 becomes accessible and the battery can by inserted in the above described manner. Alternatively, the battery compartment door 10 can be removed from the axle 28 so that the battery can be loaded into the cradle 18.
Rotation of the door 10 about the axle 28 towards the main body of the device 10 is limited by an upper section 30 of the cradle 18 contacting a lower section 32 of the electric circuit 14, as shown in FIGS. 4 and 5. The door 10 is arranged in a closed position when the upper section 30 of the cradle 18 abuts the lower section 32 of the electric circuit 14.
The lower section 32 of the electric circuit 14 includes an electrically conductive contact (not shown) that is positioned to electrically engage the electrically conductive upper section 30 of the cradle 18 when the door 10 is closed. The electrically conductive upper section 30 of the cradle is electrically coupled to an electrically conductive section of the cradle that at least partially receives the positive terminal 20 of the battery 12. These sections of the cradle 18 are electrically coupled together by any suitable means. Preferably, the electrically conductive upper section 30 of the cradle 18 and the electrically conductive section of the cradle 18 that at least partially receives the positive terminal 20 of the battery 12 form part of the cradle 18. Preferably, the cradle 18 is made wholly or partly of an electrically conductive material such as an electrically conductive polymer, for example. The electrically conductive polymer is preferably a mixture of polymer (PC/PA/PBT/PMMA or PE) and reinforced by metal powder, carbon.
The electric circuit 14 is thereby electrically coupled to the positive terminal 20 of the battery 12 when the battery door is closed in the described manner. The electric circuit 14 of the device 16 also includes an electrically conductive metal contact 34 that extends from the electric circuit 14 towards the battery compartment door 10. The contact 34 is may, alternatively, be made of a non-metallic electrically conductive material which can include, for example, electrically conductive polymer or plastic material. The contact 34 may be made of any suitable shape, whether regular or irregular, depending on the design of the door 10. The contact 34 is arranged so that it engages the negative terminal 26 of the battery 12 when the battery compartment door 10 is closed, as shown in FIG. 3.
The battery compartment door 10 electrically connects the positive and negative terminals of the battery 12 to the electric circuit 14 of the hearing aid device 16 when the door 10 is arranged in the closed position. The battery compartment door 10 is secured in the closed position for electrical communication with the electric circuit 14 of the hearing aid device by any suitable means. An example of a suitable locking means is described out below.
The hearing aid device 16 includes a switch 40, as shown in FIG. 5, that is used to turn the electric circuit 14 on and off. The switch 40 includes an on/off cover 42 that is rotatable about an axle 44 so as to move between on and off positions that respectively close and open an electric gate 46 of the electric circuit 14.
The on/off cover 42 is also mechanically coupled to a battery compartment door 10 by the locking means 48 shown in FIGS. 2 to 5. The mechanical connection between the on/off cover 42 and the battery compartment door 10 holds the door 10 in the closed position and thereby holds the cradle 18 in electrical communication with the contact (not shown) of the lower section 30 of the electric circuit 14. The on/off cover 42 and the battery compartment door 10 are mechanically coupled together such that the battery compartment door 10 cannot be readily opened unless the on/off cover 42 is first arranged in the off position. The battery compartment door 10 is thereby securely held in the closed position.
The various components of the battery compartment door 10 are injection moulded from plastic material such as Acrylonitrile Butadiene Styrene (ABS).
While we have shown and described specific embodiments of the present invention, further modifications and improvements will occur to those skilled in the art. We desire it to be understood, therefore, that this invention is not limited to the particular forms shown and we intend in the append claims to cover all modifications that do not depart from the spirit and scope of this invention.
